Auline 21700 S70 4500 mAh 22.2 V 6S Li-ion Battery (XT60)

The Auline 21700 S70 6 S 4500 mAh Li-ion Battery is the heavyweight endurance champ of FPV power. Packing serious 22.2 V output and a 70 A discharge rating, this XT60-equipped beast feeds your long-range quads, wings, or heavy-lift rigs with steady voltage and zero drama. Built with 21700 cells for maximum energy density, it’s the go-to choice for pilots who actually like finishing full packs before gravity does its thing.

Why You Want It

Because “low voltage” warnings shouldn’t be your flight soundtrack. The S70’s 6 S 21700 configuration delivers massive capacity and sustained current without sagging mid-throttle. It’s ideal for endurance builds, mapping setups, or any FPV mission that needs both range and reliability. And thanks to Li-ion chemistry, you get more watt-hours per gram than LiPo—meaning less battery swapping and more actual flying. Fewer lipos, fewer landings, more flex.
